A tank with a square base of 20 cm was
14 filled with water After another 21175 cm
3 of water was poured into the tank, it became
45 full.
- Find the capacity of the tank in litres.
- Find the final height of the water in the tank.
(a)
Fraction of the tank when 21175 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 21175
120 of the tank = 21175 ÷ 11 = 1925
2020 of the tank = 20 x 1925 = 38500
38500 mℓ = 38.5 ℓ
Capacity of the tank = 38.5 ℓ
(b)
1620 of the tank = 16 x 1925 = 30800
Final height of the water in the tank
=
3080020 x 20 = 77 cm
Answer(s): (a) 38.5 ℓ; (b) 77 cm
